Chapter 12 of Agenda 21 is titled: Managing Fragile Ecosystems: Combating Desertification and Drought. This whole chapter is devoted to the wasting of land by climate change and man's overpopulation. Desertification is a fancy word for land that is turning to desert. Here is Agenda 21's explanation.
12.2. Desertification is land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities. Desertification affects about one sixth of the world's population, 70 per cent of all drylands, amounting to 3.6 billion hectares, and one quarter of the total land area of the world. The most obvious impact of desertification, in addition to widespread poverty, is the degradation of 3.3 billion hectares of the total area of rangeland, constituting 73 per cent of the rangeland with a low potential for human and animal carrying capacity; decline in soil fertility and soil structure on about 47 per cent of the dryland areas constituting marginal rainfed cropland; and the degradation of irrigated cropland, amounting to 30 per cent of the dryland areas with a high population density and agricultural potential.
Their solution? Drag the government, international organizations, regulations, and land management policies in to fix it. Along with that are the drastic measures that need to be taken to prepare for the inevitable disaster that looms. Much like the climate change adaptation policy BHO is proposing along the UNs' side in the category Barack Obama 11/6 post, it is all based on what they think is going to happen.
But here is a video of Allan Savory talking about his solution which has been proven to work. One man, determined to find an answer, because of his love for his country.
